sale Ecotax Management (as a tax)

This module extends sale order lines so that ecotaxes are managed as taxes instead of separate ecotax lines. When you add a product to a sale order, Odoo automatically looks at the product's classification and the customer's delivery country (or the customer's country if no delivery address is set) and adds the matching ecotax tax to the line. If a fiscal position is set on the order, the ecotax tax is adapted according to that fiscal position.

The sale order line form shows two computed amounts: the ecotax amount per unit and the total ecotax subtotal for the line. These are recalculated whenever the taxes, quantity, product, company, customer or delivery address change.

Because the ecotax is now a tax, the existing ecotax line list on the sale order line is made read-only, so users cannot edit it manually. When the order is invoiced, the ecotax information is passed to the invoice line only when there is an actual ecotax amount; otherwise it is left out.

This module is installed automatically when both the sale ecotax and the ecotax tax modules are present. It touches the sale.order.line model and the sale order line form view.
